To all whom t may concern.'

Be it known that I, EMORY J. Lrers, a citizen of the United States, residing at borough of Fountain Hill, in the county of Lehigh and State of Pennsylvania, have iii-- vented certain new and useful Improvements in Doubling-Machines, of which the follow-- this has considerably kept down the speed and so limited the production of such machines, thus: The broken end will become more or less wound in on the bobbin with 'the complementary unbroken end or endsmaking it correspondingly more or less diiiicult and time-wasting for the operator to find itk-according to the number of revolutions the bobbin makes after the breakage occurs; it. would be impracticable at any suitable speed to stop the bobbin instantaneously,and' if it is stopped gradually (which is the usual way, as by raising it out of contact with'its rotating driver) then the speed of the machine can not be very great without so much of the unbroken yarnl becoming wound on the bobbin after the break occurs and by the V time the bobbin runs down and stops that it would make it 'unduly tedious and timewastin to attempt to locate the broken end.

.By tie present invention this difficulty is overcome and a very much greater speed is possible, with consequently and correspondingly greater output. My invention contemplates means which, instead of checking the rotation of the receiving bobbin, stops the doubling operation when a yarn breaks by disrupting the remaining yarn 'or yarns. In the examples herein set forth the supply bobbins are arranged so that each delivers over one end or head thereof toward the receiving'bobbin rather than sidewise; this has several advantages, the most important of which is that the rotating of the supply bobbins (usually accomplished where the delivery is sidewise from these'bobbins by the ull of the yarn thereon) does not have to be considered, and so the speed may be considerably increased on that account. In

` some cases I have provided for the supply bobbins being arranged side by side; but I may also arrange them with their axes in substantial alinement andv roectin toward the receiving bobbin, whidh ils ver? advantageous because among other things itfmakes it possible for my aforesaid -means for' stopping `the doubling operation to be devised, as. will appear, so as to operate as a tension and also for a twist to be put into i regulator the doubled product, with a certain conseguent advantage hereinafter .set forth. My inventionl contemplates, in addition tothe foregolng certain provision for facilitating the attendants work in piecing the broken ends together` when av stopping of the doubling operation on account of breakage has been effected.-

Fig. 4 is a horizontal sectional view taken Justabove the supply bobbins in Figs. 2 or 3; v Figs. 5 and 6 are front and side elevations of a doublin unit embodying my invention two-.yarn doubling operation;

Figs. 7 and 8 are front and side elevations of a .doubling unit embodyin my invention in still another form thereo and I Fig. l9 is an inside elevation and a section on line 9-9, Fig. 4, of a detail.

In all the forms shown, A designates the frame of a doubling machine; B its lower rail for the support of the supply bobbins; C a palr of bars forming its top rail; D its intermediate rail; E a suitabl rotated shaft carr ing the rotary drivers 'on t e top rail havin guides G and seats Gr2 for the receivingobbin spindles; and H" the suitably reciprocated traverse rail. a in all the forms shown designates the supply bobbins.- and b the receiving bobbins.

`Referring, first, to Figs. l to 4: The supply bobbins a, standing upright, are arranged in two pairs, one directly in front of the other, and each bobbin is preferably set in a skeleton frame c arranged on the rail B having, at the top and nearly as high as the bobbin, a ring c on which is a traveler c2 (Fig. 9) to keep this traveler from binding against the ring as it moves around the in another ormthereof and applied to a' G bracketsv ion same (that is, to preserve it as nearly as os- .Iggybe a depending'loopcot the wire ot'which f the traveler is formed. v"llhe yarns from the tour bobbins a, enga ed with the guides lll e on the traverse rail in the'usual way, pass for doubling onto the single bobbin b, which when driven by the driver F has its spindle o -b' engagedinV the guides G'of `the brackets G and when idle has its spindle supported ing eyes are in alinement =with the res ective axes of the four bobbins an; these con ne Athe ed' its bobbin and plays around the same to definite positions. ln the present example i themeans for stopping the doubling 'operation ma be re arded as divided-into two separate y mova le portions, to wit, the upper or yarn-engaged or detector portion and the lower or disrupting portion, theformer being adapted on movement to move the latter. The lower portion or disrupter is a llever e pivoted on la horizontal transversely extending pin f (so that the lever moves )in a vertical front-to-rear plane) 'which is A-mounted in a bracket g projecting from rail D. The lever extendsabove its pivot or fulcrum and hasv above the same a trans- -versely extending or T-he'ad-forming portion e 'and also a rearwardly reachin threaded stem e2, on which is screwedan a justing weight e3; the lower end ofv the lever bins of both pairs, and this forwardly bent portion has two transverse cross-arms e4. The weight of the lever, which moves quite freely on its ilcrum, normally retains it in about the positionl shown by full lines e@ in Figs. 2 and t, z'. e., so that the ends of its cross-arms are just clear of the cones formed by the yarns as they are delivered from the bobbins a; if the lever lis shifted so as to move its lower` end forward v(dotted lines,

45 Figs. 2 and 4) the cross-arms, being interposed in the paths of the yarns, will disrupt them, to which end it is preferablen to give the, ends of the cross-arms a slight hookshape, as shown in Figs. l and fi, so as to insure their edectually catching and so disrupting the yarns in the position indicated. It will be understood that the osition in which the lever is normally retalned (z'. e., its idle position) may be nicely determined by adjusting the weight es. The upper or detector portion'of the aforesaid means condii sists of a set or fallers l1. each pivote'd on a pin f at its lower end and having its upper end bent. forward and equipped with a @il bobbins a being respectively engaged with these yarn-guides, each of which is normally held by the yarn in about the position shown in Figs. 2 and 4 but which, when released 65 bythe yarn, will under the inuence of a lrearwardly a: ainst one of. thejarms of the in the rests G2. Suitable yarn guides E are arranged -on rail D so that their yarn-guild cones formed by the yarns as each is drawn` is bent forward, standing between the bob-v yarn-guide t, the several yarns from the j *mensaje ranged two fon onev and 'two onthe other side ot the plane ,of movement v.et lever e' and so that eachy when it falls back will press 7@ T-head of said lever and so move the same to the dyarnlisrulmting position alreadyv ex'- plaine A transverse bar il of the machine may limit the forward movement ot the fall-1 ers. lt will be understood that if any yarn te breaks whilefithe doubling operation 1s prog'- ceeding the falling back of the corresponding taller and consequent vmovement of thedisrupter e results in the disrupting ofall the other yarns, the-'bobbin b continuin to rotate, howevenuntil it. isl stopped. `@gon observing that the doubling operation as been stop ed the attendant takes the bobbin t from t e machine and finds the broken ends preparatory to piecing them with the broken ends of the yarns extending from the bobbins a, which is readily. accomplished 1t the mechanism is adjusted so that von the breaking of a yarn the others willbe disrupted with promptitude and therefore said 9e ends are not'circumferentially far apart on bobbin rlhe attendant then restores the bobbin .b 4to vthe machine, placing it however in the rests G2, in order to piece the yarns, and as the yarns on bobbins a should be free to travel around them without interference by the disrupter at this time ll provide means controlled by the bobbin b for controlling the position of the disrupter, or more speoically, for holding the disrupter lo@ in the idleor normal position (full lines, Figsg?, to. 4) whenever the bobbin b is out of position to be driven by driver' F, thus:

0n a transversev n 'i projecting 'from a bracket j on rail is fulcrumed a detent leb lever la having its lower end bent laterally and traversing the upper end of lever e and its upper end crooked rearward and weight ed and adapted to bear against the whirl b2- ot the spindle for bobbin b. When the bobu@ gli bin is present in vits guides G', or driven position, the whirl b2 holds detent lever It 1n the (idle) position shown in Fig. 2, so that lever e is free to move to disrupting position; but when the bobbin is removed 115 for the purpose ot findin the broken ends the detent lever falls ackward and so shifts the lever e to the idle position (Fig. 3) and holds it there until, the attendant having meanwhile placed the bobbinin the 12a rests G2 till the piecing of the yarns is comleted, the bobbin is restored to the guide and so shifts the detent lever back to its normal or idle position. v

Referring, now, to the form shown in me Figs. 5 yand 6: Instead of there being a plurality ot detector members, one for each yarn, controlling-aJ disrupter member commorera eration) separately movable sto ping `means each adapted to dlsrupt one of t e yarns but' alread controlled by the other yarn'. In the example' shown each lof these means consists of a lever c Z fulcrumed on a pin'fml to move freely in aL vertical front-to-rear planeiand having its" upper on detector end bentforward and equippedwith a guidel for one of the alliil.V

and its lower or disrupting end bentl aterally and downwardly and terminatin in a hook Z. The yarn normall holdstlie evers in the position shown in ull lines inv Fig. 6, where the hook of each is just clear of the yarn-cone of the relatively oppositebobbirr a; but if one of the yarns breaks the correv spending .lever falls back to the dotted line with position and its hook Z2 interfering) obbin the play of the yarn of the opposite around the same, disru ts it'also. n denotes.

a detent lever substantially the same in construction and function as the detent lever lc described.

. In igs. 7 and 8 the supply bobbins a are l arranged one above the other. Here again (where the doubling operation is of the two# thread type) there are separately movable stopping means each adapted to vdisrupt one* ofthe yarns but controlled by the other yarn. One bobbin a is arranged on the lower rail B and the other on the lntermediate rail l), in-

-axial alinement with each other and with the receiving bobbin b, and each in a skeleton frame c havingrring c referalolyl pand traveler c2, as in Figs. 1 to 6. he detectors are' levers ol fulcrumed on pins p one above each bobbin, each having at its forward end a yarn-guiding eye o (preferably circular) axially alined with the bobbins and on its rear end-an adjusting -weight o2. The disrupters arelevers fulcrumed on pins r adjacent the respective'bobbins and so'as to be movable into and out of the paths of the l yarns travelin around the bobbin heads 1n beingdelivere A link s pivot-ally connects the detector adjacent each bobbin withthe relatively opposite disrupter. The stopping operation in this case will be Substantially the same as in the form shown in Figs. 5 and 6.- t is a detent lever serving the same purpose as the detent levers k and n already described; that is, whenever the receivingl bobbin Z is removed from its guides G the weight of the lever moves it to the dotted line position in Fig. 8, so that arms t thereon engage bends o8 in the detector levers o and by camming them up on their fulcra shift and hold theA corresponding disrupt/er levers g clear of the yarns. The yarn from the ,upper Abobbin is passed through a uide u axially alined with said bobbin and t e yarn from the lower -bobbin is assed axlally through the upper bobbin, u 1n Fig: 8 being a yarn guide 1nv the rail D that is alined with the bore or hole of said bobbin. The arrangement shown inFigs. 7 and 8, it will lof wm be apparent, results finthe "of lthe l yarn from 'the upper bobbin around that from the lower bobbin. The doubled threads are thereforev bound together, in cnsequence of whichwhen theyl pass to thespinning operation it is unnecessary to resort` to alii'er for holdingA them together o r subject* them to any preliminar p treatment to'faccomplish T 'is arrangement presents fpurpose. A the `urther .advantage that each vdetector lever, being placedimmediately above a bobbin, serves as a regulable means` to preserve such tension ontheyarns as Ymay be suit- 'able or desirable according to their tensile strength and other conditions. .si

In the examples -herein set forth the disrupting is'an incidentv of checkin the advance of the yarn under-the dra of Athe receiving package-by checking the travel ofv the yarn around its suppl package in the .delivery `of the coils thereol ,-the yarn partin where it hav pens to be weakest.
